使用 Docker 和 Traefik 搭建 WordPress

其實不止一次想從新提筆聊聊 WordPress ，然而以前由於定製代碼量比較多，許多文章不得不擱置在草稿箱中。恰逢假期，整理草稿箱，從搭建開始聊起吧。web

本文將使用 Docker、Compose、Traefik 對 WordPress 進行搭建，完整操做時間應該在十分鐘內。sql

爲何選擇 WordPress

每當聊起 CMS 類軟件，聊起社區資源豐富，不禁地會想到一個「萬金油」：WordPress ，官方數據稱：docker

Over 60 million people have chosen WordPress to power the place on the web they call 「home」數據庫

Hundreds of thousands of developers, content creators, and site owners gather at monthly meetups in 436 cities worldwide.apache

WordPress 爲 33% 的互聯網提供支持。編程

許多人對它的印象還停留在執行速度慢、安全性差、代碼臃腫的博客系統上。可是事實上，通過十幾年的迭代，它的大版原本到了 5.0 （PHP 主流運行時也來到了 7.0 時代），性能早已不是問題、安全問題只要作適當的防禦能杜絕絕大多數。瀏覽器

emmm, 代碼確實仍是挺臃腫的。

基於官方鏡像

官方提供了容器鏡像，鏡像下載能夠直接使用下面的命令：

docker pull wordpress
複製代碼

可是爲了更好的配置使用，咱們使用 compose 的方式進行編排，將下面的內容保存爲 docker-compose.yml ：

version: '3'

services:

  wp:
    image: ${WP_IMAGE}
    restart: always
    networks:
      - traefik
    environment:
        WORDPRESS_DB_HOST: ${DB_HOST}
        WORDPRESS_TABLE_PREFIX: ${WP_DB_PREFIX}
        WORDPRESS_DB_NAME: ${DB_NAME}
        WORDPRESS_DB_USER: ${DB_USER}
        WORDPRESS_DB_PASSWORD: ${DB_PASS}
    volumes:
    # 若是你有定製上傳文件尺寸的需求
    # - ./config/php.conf.uploads.ini:/usr/local/etc/php/conf.d/uploads.ini
      - ./wp-app:/var/www/html
    labels:
      - "traefik.enable=true"
      - "traefik.frontend.rule=Host:${WP_DOMAINS}"
      - "traefik.frontend.entryPoints=https,http"

  mariadb:
    image: ${DB_IMAGE}
    restart: always
    container_name: ${DB_HOST}
    networks:
      - traefik
    environment:
      MYSQL_DATABASE: ${DB_NAME}
      MYSQL_USER: ${DB_USER}
      MYSQL_PASSWORD: ${DB_PASS}
      MYSQL_ROOT_PASSWORD: ${DB_ROOT_PASS}
    volumes:
      - ./data:/var/lib/mysql

  pma:
    image: ${PMA_IMAGE}
    restart: always
    networks:
      - traefik
    environment:
      MYSQL_USER: ${DB_USER}
      MYSQL_PASSWORD: ${DB_PASS}
      MYSQL_ROOT_PASSWORD: ${DB_ROOT_PASS}
      PMA_HOST: ${DB_HOST}
    labels:
      - "traefik.enable=true"
      - "traefik.frontend.rule=Host:${PMA_DOMAIN}"

networks:
  traefik:
    external: true
複製代碼

若是你還不會使用 Traefik ，能夠翻看我以前的文章，這裏不作過多贅述。

爲了可維護性，咱們將容器鏡像版本信息，應用域名，數據庫配置等抽象爲單獨的環境配置文件 .env，內容示例：

WP_IMAGE=wordpress:5.1.1-php7.3-apache
WP_DOMAINS=wp.lab.com,wp.lab.io
WP_DB_PREFIX=wp

DB_IMAGE=mariadb:10.3.8
DB_HOST=wp-db
DB_NAME=wordpress
DB_USER=wordpress
DB_PASS=wordpress
DB_ROOT_PASS=soulteary

PMA_IMAGE=phpmyadmin/phpmyadmin:4.8.2
PMA_DOMAIN=pma.wp.lab.com,pma.wp.lab.io
複製代碼

當兩個文件都保存完畢以後，咱們執行 docker-compose up 命令，你將會看到許多日誌信息，當看到相似下面的信息時，WordPress 環境便準備就緒啦。
